Why AP cannot get ip address from WLC or external DHCP server?

wfqk — Mon, 05 Jul 2021 14:29:49 GMT

Hi, I configure DHCP at Cisco switch 3560 as the below show some relative configuration. AP1140 is connected to the switch port. but AP cannot get ip address. From the AP console, we can see "%CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP" WLC is connected to the switch via trunk

Also, I tried configuring internal DHCP of WLC, but it still cannot work. Anyone can give some suggestion? Thank you

Switch#

Hi There.

Is your SVI 10 or interface vlan up?

you can check it using " show ip inter brief"

be sure that vlan in layer 2 exist.

Thanks for your reply

Thanks for your reply

Yes SVI 10 is up via checking "show ip inter brie"

Well, you configuration on

Daniel Ordóñez Flores — Fri, 04 Aug 2017 18:36:54 GMT

Well, your configuration on port 3 looks fine, if you can console to AP use this command:

"debug dhcp detail" and please share the output.

Btw, where is your WLC

Daniel Ordóñez Flores — Fri, 04 Aug 2017 18:39:59 GMT

Btw, where is your WLC management interface? is on VLAN 10 too?

yes, management interface is

wfqk — Fri, 04 Aug 2017 19:02:20 GMT

yes, management interface is also in vlan10

below is debug info:

Be sure that only 3560 DHCP server is working and delete the line: lease infinite

ip dhcp pool Vlan_10
network 10.1.1.0 255.255.255.0
default-router 10.1.1.10
lease infinite

I see the offering message from DHCP Server but it looks some issues with timers.

Actually, I see the ACK

Daniel Ordóñez Flores — Fri, 04 Aug 2017 19:51:12 GMT

Actually, I see the ACK packet from DHCP server operation and I see the AP got 10.1.1.43 ip address.

Now, If we already have an IP Address we need to use another command to check why is not join.

Please share the outputs of these commands:

On the AP:

show log

show capwap client rcb

debug capwap client detail

debug capwap client events/error

On the WLC:

show msglogs

show traplogs

debug mac addr <AP Ethernet/Radio mac>

Which is the WLC ip address?

Post "show sysinfo" & "show interface" summary output from your WLC. It looks like WLC got multiple interfaces and AP discovery message is coming via those dynamic interfaces

To test it out, you can statically point your AP to WLC management IP address and it should work as a workaround.

LAP#capwap ap primary-base <WLC_Name> <WLC_Mgt_IP>

on you AP CLI, configure below

LAP#capwap ap primary-base Cisco_68:ca:03 10.1.1.9

and see if it go and register to WLC.

Since WLC is configured with US country code, I would verify AP regulatory domain matches (ie -A regulatory domain)

Rasika Nayanajith — Sat, 05 Aug 2017 00:34:23 GMT

Looks like AP got some sub-interfaces created (H-REAP config).Is that configuration done by you ? was this AP previously in use ?

If you are ok with erase AP config, try below

LAOP#debug capwap console cli
LAP#erase /all nvram:
LAP#reload

Once reload point it to WLC

AP#capwap ap primary-base Cisco_68:ca:03 10.1.1.9

Rasika Nayanajith — Sat, 05 Aug 2017 02:03:39 GMT

Since it is H-REAP you can try below configuration of your switchport that connect to this AP

interface GigabitEthernetx/x

switchport trunk encapsulation dot1q

switchport trunk native vlan 10

switchport mode trunk

spanning-tree portfast trunk

If that does not work, you have to erase you config of the AP and put the switchport back to access mode.
